Abstract

The hydrocyclone assembly has a number of hydrocyclones (1) each with at least one inlet (2) and one outlet (3) for cleaned fiber suspension and an outlet (4) for the reject fraction. At least one connection for the hydrocyclone (1) has a flange (6), secured to the distribution/collection unit (5) by screw bolts (9) mounted to the wall (7) of the unit (5). The screw bolts (9) are welded to the wall (7) of the distribution/collection unit (5). Two screw bolts (9) are fitted for each connection, at points with the min. gap to the flange (6). At least one seal is round the connection into the interior of the distribution/collection unit (5), with a thickness flanking the wall opening which gives a larger dia. than the opening through the wall (7). The outer dia. of the seal in position through the wall opening is at least 2 mm smaller than the wall opening dia. The drilling through the seal is conical, tapering in the direction of the flange (6) mounting, and the disk surfaces of the flange (6) are not in contact with the seal. At least two connections can be adjusted in relation to each other, at the hydrocyclone, and then locked in position. The center axis of the hydrocyclone (1) is at right angles or parallel to the main flow direction at the distribution/collection unit (5). The distribution/collection unit (5) has a flow section with a cylindrical side wall (7) with openings for the feed (2) and the cleaned fiber outflow (3) or the reject fraction outflow (4). It has an inner dividing wall to separate the flow cross section with the feed upstream of the wall and the outflows downstream of it. The outflow openings (3,4) are evenly distributed round the circumference of the unit. The side wall (7) has the outline of a regular polygon.
